Application filed May 28,1919. Serial no. 300300.

To all yreomjz't mwy concern:

Be it known that I, WILLIAM SCHWARTZ, a citizen of the United States, and a resident ef Scottdale, in the county of Westmore- 3 land and State of Pennsylvania, have in,-

muted anew and useful Improvement in Aritiskid-Chains; and I do hereby declare the followin to be afull, clear, and exact description t ereof.

7 .mohiles'and other like vehicles.

use my improv scribe the same more fully, referring to the The object-of my invention is to rovide cheap, simple and efiicient anti-ski chain, which can be easily andfquickly applied to the ordinary automobile tire, and which when in lace will form a chain which will be fiexib e in all directions, will prevent side skidding and will give some protection to the tire at the sides of the same. Y

To these ends my invention consists, generally stated, in the novel arrangement, construction and combination oi parts, as here- :after more specifically set forth and described and claims.

To enable others skilled in the art to'which my invention a pertains to construct and anti-skid chain, I will deaccompanying drawing, in which:

re 1 is a side view of a vehicle wheel ahowin my improved anti-skid chain in position, or use; p

Fig. 2 "s an enlarged cross-section of the tire and rim of such wheel showing the chain applied thereto,

ig. 3 is a plan view of a portion of the chain removed from the-wheel;

Fig. 4 is a side elevation of the same;

Fig. 5 is a perspective View of one ofthe meadchai-n links, and a i 6 1s a-side view showing the lock for connecting the ends of the tread chains.

Like symbols of reference herein Indicate like parts ineachof the figures of the drawis illustrated in the drawing a represents the ordinary automobile wheel and t e usual felly b which is provided .with the usual pneumatic tire 0 around the same, and pro-.

rided with the tread portion 0!.

particularly pointed out in the My improved anti-skid chainA comprises the two circumferentially arranged tread chains 1 each of which is placed on each side of the tread portion d on the tire c and is adapted to bear against the same. These two tread chains 1 are connected with each other by a series of cross or traction chains 2, which are spacedapart from each other and extend over and are adapted to .bear against the tread portion don the tire a. The chain A is supported on the tire c of the wheel a, by means of a series of attaching chains, 3, which are connected to the tread chains 1 by being secured at one end to one of said tread chains and detachably secured at the other end to the other of said tread chains by ,means' of the ordinary sprin clip 4. These attaching chains 3 extend om the tread chains 1 around the base of the tire c-and under and around the folly b, and in order not to mar or in'ure such felly, the. chains 3 are provided with a tubular casing 5 surrounding such chains, which is preferably formed of rubber or other suitable resilient or flexible material for hearing against such felly.

The links 6 of the tread chainsl'are each provided with the eyes 7 and 8 at each end of the same for being connected to each other, and formed from a sin 1e piece of metal. In the formation of the inks 6 from the metalrod, the end of such rod after forming the e e 7 is welded to the connecting portion 9 etween the eyes 7 and 8, as at 10, while the other end of such rod after forming the eye 8 is turned down to form the outwardly projecting portion 11. In such formationthe rod 13 twisted, so that each of the eyes therein are at right angles to each other, with the said projecting portion 11 also at right angles to said connecting portion 9 and parallel to the eye 7. These portions 11 are adapted to extend along the sides of the tread portion (1 of the tire I: on the radii of the wheel a, and such portions are provided with the pointed or sharpened portion 12 at their outer ends.

The eyes 7 and 8 of the linl rs 6 being thus formed at right angles to each other as sume such when place around the tread d on the t1re c, and thus allow the face of the eyes 7 to lie against such tread.

The ends of thegtreaid chains 1 are deosition in the tread chains 1.

tachahly connected together and locked by means of the locking bar 13' which hingedly connected at 14 to one end of a link 15 and which is connected by a ring 16 thereon with the eye 7 on oneend link (5, whil the opposite end of such bar is turned outward. as at 13 and is adapted to enter a ring 17 on the eye 7 on the other and link (i.

It will thus be seen that by reason of the tread chains on my improved anti-skid chain the direct wear upon the tire will berelieved as far as possible,thereby. prolonging the life of such tire and preventing undue abrasion while the wheel containing such tire is'in motion or traveling, while the use of such chains will hear so tightly against the sides of the tire and by reason. of the constrru tion and placing of the sides of the links against such tire sides,,the liability of side skidding is overcome and protection given the tire against injury from coming 1n contact with articles picked up on the roads or highways or coming against the sides of the same.

It will further be seen that the use of the outwardly projecting portion having sharpened ends will permit such ends to engage the roads or highways to prevent side kid ding by taking into such roads or highways and thereby enabling positive engagement with such roads or highways at all times. and the use of such projecting portion centrally of the link will keep the chain from tip )ing when in place.

t will be obvious that any suitable means can be employed for holding my improved chain on the tire or locking the same when in place on the tire. while various other modifications and changes in the design and construction of my improved anti-skid chain within the scope of the appended claims may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages. I

What I claim as my invention and desire to secure by Letters Patent is:

1. An anti-skid chain for wheels having elastic tires comprising a cireunrterentially arranged chain provided with twisted links having an eye at each end, and projections on said links extending outwardly therefrom and from one of said eyes and suljistant-ially parallel with the other.

An anti-skid chain for wheels having elastietires comprising a circumferentially arranged chain provided with twisted links having an eye on each end. and projections on said links extending outwardly therefrom and from one of said eyes and substantially parallel with the other, said pio jections having sharpened outer ends.

3. An anti-skid chain for wheels having elastic tires comprising a circumfcrcn'tially arranged chain provided with twisted links having an eye at each end and connected hy an intermediate portion. and projections on said links extending outwardly therefrom and from one of said eyes and suhstantialtv parallel with the other, said projections being substantially centrallyof the links and intermediate portions.

4. An anti-skid chain for wheels having elastic tires comprising a circuniferentially arranged chain provided with twisted links having an eye at each end and connected by an intermediate portion, and projections on said links extending outwardly therefrom and from one of said eyes and substantially parallel with the other. said projections being substantially centrally of the links and intermediate portions. and provided with sharpened outer ends.

In testimonywhereof. I the said Wilma n Scnwan'rz. have hereunto set my hand.
